Are you using Unreal Engine 4? Or where did you get the term "blueprint" from?

A blueprint is a technical drawing of a home or product used by the manufacturer to build something.

Figuratively, a blueprint is a technical specification used to design software. In terms of C++ language elements, a template is a blueprint -- the compiler uses it to generate a class.

For example,

template <typename T>
struct point
{
  T x, y;
  point(): x(T()), y(T()) { }
  point( const T& x, const T& y ): x(x), y(y) { }
};

int main()
{
  point <int>    p1( 2, -3 );
  point <double> p2( .7, -3.1 );

The compiler uses the information about a 'point' to generate two distinct class types: an integer point and a floating-point point.

Hope this helps.
